For those of you gardening in British ColumbiaÃ¢Ë†â€™congratulations! You`ve been enjoying a lovely warm summer, but the rest of Canada, well, we're still waiting for summer to arrive. So far, Ontario's summer has been cool and wet. I recently read an article in the Globe and Mail, and it said that this has been the coldest July in 17 years in southern Ontario. The average temperature has been three degrees below normal and the average rainfall; well let's just say my gardens are still soaked! The only good thing about this rainy July is that my grass is lush and green. Of course, I have to mow it every week, but normally at this time of year it's already become a crunchy brown carpet.

Because of the rain, some of the plants in my garden are suffering from a serious case of powdery mildew. Powdery mildew is caused by Sphaerotheca fuliginea. The leaves on my phlox, roses, cucumbers and even the Manitoba maple tree are covered with grayish-white, powdery spots. Although powdery mildew isn't pretty, it is rarely fatal, so I'm not that concerned. To combat this pesky fungicide, I prune the infected plant parts and get rid of them. This helps improve the air circulation around the plant. Since powdery mildew likes a moist, humid environment, this helps combat the infection. You could apply fungicide, but there is also a home remedy using baking soda, which helps reduces the plants risk of becoming infected in the first place.

Homemade Powdery Mildew Fungicide

3 ½ litters of water

1 tablespoon baking soda

½ teaspoons liquid soap

A few days prior to applying the mixture, water your plants well. Avoid treating the plant in direct sunlight. Apply the homemade fungicide with a spray bottle, ensuring you get full coverage.

I've also heard spraying a concoction of milk (1 part milk to 9 parts water) that helps reduce a powdery mildew infection, but I've never tried this remedy myself.

I've had a terrible problem with squirrels this past season. They carried off several of my veggie plants, and a few summer bulbs, and dug up some of my seeds. A lady up the street feeds them peanuts, so I find peanut shells all over my yard as well as random holes from their relentless digging.

Earlier this season I would sprinkle cayenne pepper all over my gardens and chase squirrels out of my garden like a crazy person. A few folks here at the office were horrified about the cayenne as they had heard that if the squirrels get the spice on their paws, they'll rub it in their eyes and scratch at their eyeballs. A Canadian Gardening colleague did a little digging and found some information from the Humane Society, which recommends cayenne pepper in the garden and I found a page online that I figure makes it OK if it’s coming from a society that protects animals. The only problem with cayenne is you have to constantly reapply after giving your garden a good soak or after it rains.

In the recent issue of Toronto Life, I read Brent Preston's memoir about becoming a farmer. Brent's battle was with groundhogs and insects. To control the destructive flea beetle from ravaging his crops, he covered his plants with row cover, a finely woven fabric that allows sun and water to pass through but keeps insects out. I'm wondering if this would help deter the squirrels from my plants and seeds–at least until they're strong and sturdy. I think I saw an example of row cover last week when I was in the Bruce Peninsula. We came across Harvest Moon Organic Bakery and Sculpture Gardens while looking for a mountain biking trail. At the end of a long driveway we came across this lovely little bakery with the most delicious treats. Part of their vegetable garden was covered in a light cloth, which appears to be row cover. I think I might try it next year.

I've become a frustrated bat house landlord. I feel like I need to put up a flashing sign saying `Vacancies` or maybe put an ad in the local newspaper.

Bat House for Rent
Located in a great neighborhood, this ready-to-move-in bat house is mounted on the side of a two-story home–providing excellent home-protection against hungry predators. The interior of the home has been furnished with unfinished wood, perfect for gripping and hanging around. Painted a stylish shade of black, the house receives ten hours of direct sunlight a day–you'll never have to pay another heating bill. Local gardens provide a smorgasbord of night-flying insects such as moths, beetles and mosquitoes and the backyard swimming pool is a popular destination for late night drinks.

It's almost been a year and we still have no bat tenants. My husband, Christopher built the bat house after we kept seeing bats flying around our yard at dusk, so obviously they're in the neighborhood. Christopher spent an evening researching how to build a bat house, so we know it meets their requirements. Maybe we need to lower the rent?

I was so excited about my veggie garden this year. We carved out a whole new area in the backyard and I was so optimistic about reaping a bountiful harvest. Sadly, I had a real problem with squirrels… they carried away all but one of my eight cucumber plants, all but two of my eggplants and dug up half my seeds. On the bright side, my two plants that I got at the President’s Choice Lawn & Garden event–a zucchini and a sweet pepper–are doing amazing and I have some hot peppers, onions, tomatillos, beets and bush beans that will hopefully yield at least a couple of vegetables.

But then I went to my sister’s place the other night and her balcony garden is doing amazing! She has green tomatoes already and her plants are all big and bushy. My garden is quite stunted by comparison. I’m thinking maybe I need more nutrients in the soil. Needless to say, I was a little envious of her success. But I still hold out hope that my plants, however stunted, will give me a late harvest. Last year I was still picking tomatillos and tomatoes in November! Fingers are crossed.

What do you wear when you garden? Well a gardener in Collingwood, ON was recently given some fashion advice from the OPP after they received reports of a man wearing an ill-fitting thong while gardening. Now I don’t know about you, but I don’t imagine gardening in a thong would be very comfortable. But then again, if you’re having fun in your garden and you’re not offending your neighbors, does it really matter what you're wearing? Maybe the thong-wearing gardener should invest in a privacy fence around his backyard–he could even claim the expense under the Home Renovation Tax Credit!

Of the 36 trees to choose from, I picked a Ginkgo (Ginkgo biloba) to be planted in my front yard by the City of Hamilton's Street Tree Planting Program.

Shortly after moving into my house, I called an arborist for a quote on having an old maple tree removed from the corner of my property. It had been dead for sometime and was leaning precariously towards my driveway. The arborist came to look at it and told me it would cost $350 to remove it, but then he mentioned that since the tree was on city property, I should call them to see if they would remove it free of charge. I certainly appreciated his honesty and willingness to save me some money, even if it cost him the job.

After calling the city to enquire about removing the tree, they came out to verify it was on city property and it was! They came back a few weeks later, removed the tree and left behind some brochures on the city's tree planting program. Not only did they remove the tree and stump free of charge, they also offered to plant a new one. I was surprised I had never heard about the tree planting program. Occasionally the city will canvas neighborhoods to plant trees in suitable locations, but otherwise, it seems the program is one of the best-kept secrets in the country.

The gingko, also known as a Maidenhair tree, has an angular crown and erratic branching pattern. The fan shaped leaves are truly unique.

Whether you live in Kelowna, Simcoe, Kingston, or Charlottetown, most Canadian cities offer a tree planting program. These programs were created to plant trees on city owned street allowances fronting residential properties for free. Homeowner are able to choose from a variety of trees native to North America, imported from Europe and Asia and hybrid varieties. Some cities have taken the program a step further by offering residents subsidized backyard tree planting. LEAF (Local Enhancement and Appreciation of Forests) is a non-profit group dedicated to improving Toronto's urban forest.

If you can find them among the ever-growing piles of garbage in Toronto, abandoned newspaper boxes can be an unsightly blight on our street corners. Karina at Canadian Gardening magazine forwarded me a link yesterday afternoon to a local blogger’s attempt to beautify our city. ‘Blade Diary’ actually built wooden flower boxes this past spring that fit perfectly inside some of these abandoned, tagged garbage targets. I guess once some of the owners found out they gave the flower boxes the boot and starting using them again. Too bad…I like the petunias better.

Hopefully you've been hanging on to all your garden centre receipts this year because the Home Renovation Tax Credit covers a number of garden related items. This is the perfect excuse to buy more plants! I'm planning on building a pond in the garden next year, so not only am I going to wait until the garden centres have their annual summer clearance sales, I'm also going to use my receipt for the tax credit. Who could ask for anything more?

One of my most treasured houseplants is my Hoya carnosa `Snowball` or simply known as a hoya or waxflower. Native to Eastern Asia and Australia, H. carnosa is one of 100 species in the Asclepiadaceae (milkweed) family. This tropical vine has dark, green leathery leaves that leak a milky sap when damaged.

My hoya is probably over thirty years old and has been passed down like a family heirloom. It was originally my grandmother's plant, who gave it to my mom, who in turn gave it to me.

Like clockwork, it blooms twice a year, once in July and again in January. It has clusters of attractive, star shaped, white blossoms with red centres. It's spectacular when it blooms. Right now, it's covered with dozens of flowering clusters.

I've already removed a handful of flowers that have finished blooming. The waxy flowers look fake, but I assure you they are real. Once the blooms opens, they are extremely fragrant, especially at night. I'm not sure why the fragrance increases at night, but the sweet scent easily fills my entire house. I've heard of some people removing the flowers because the fragrance is so strong.

So what's the secret to my hoya's success? Simple–I ignore it. I occasionally water it and rarely fertilize it. I did repot it a few years ago and replaced the soil, but other than that, it just hangs in my dinning room window. The new shoots grow quickly and it isn't until they've grown a few feet that they get leaves. There have been a few occasions where I've discovered new vines that had weaved their way through the strings of the blind, with full-sized leaves stuck in between. Unfortunately, the only way to remove them was to remove the leaves and pull the vines through. A hoya will bloom more frequently if placed in direct sunlight, but they'll also tolerate low light.

If you're looking for an exotic houseplant to grow, consider bringing a hoya home. Notoriously long-lived and hardy, these trouble-free plants are ideal for beginner and experienced gardeners alike.

I've spent most of life playing in one garden or another. Both my grandmother and mother nurtured my green thumb from an early age. My Oma could make anything grow and she happily shared her gardening secrets with me as we puttered around her garden. I remember spending warm summer afternoons picking red currents for jam or munching on cucumbers freshly picked from the veggie patch. My mom's garden was always brimming with colourful blooms and she was never upset with me when she caught me stomping through her flowerbeds to pick the tulips, peonies, or dahlias. Instead, she gave me my very own garden where she encouraged me to explore and get my hands dirty.

It seemed only natural to study horticulture, landscape design and then publishing. During my summers and school holidays, I worked at the Royal Botanical Gardens in Burlington, Ontario as a student gardener. I was thrilled to have the opportunity to play in a public garden, where so many experienced gardeners have left their own `gardening fingerprint` by nurturing the vast collection of plants. I also worked at a few local garden centre where I played in the production and retail facilities. I did everything from working as a cashier and customer service rep, to drawing landscaping plans, to hosting seminars, but what I loved most was working in the greenhouse. I never truly appreciated how much time and effort was spent growing the plants behind the scenes. The whole process is very complex, from ordering the plugs, to planting, pinching, watering, fertilizing, replanting and then watching the swarms of gardeners scoop them up on the May long weekend. What an incredibly rewarding experience. Each season brought a new crop to nurture–annuals, mums, poinsettias, hydrangeas, Easter lilies–the list goes on and on.

From my first garden as a child, to an apartment filled with houseplants and a balcony brimming with containers, to a postage-sized townhouse plot, I've continued to play and learn. Today, I garden on a mature 75×175-foot lot an hour west of Toronto, which I share with my husband, daughter, dog, and four cats (much to their dismay, my feline friends are only permitted to admire the garden from indoors). Although it's a work in progress, it truly is my gardening playground! A little fun in the garden is good for your soil!
